Crane Electrification

Crane electrification was one of the most popular uses of the U-S Safety Trolley product suite when it was first introduced, and this remains the same today.

Span-Guard was the first of the joint-free crane conductor systems introduced decades ago, and has been powering cranes ever since. Developed first in the 1950s to meet the conditions of steel mills, the system’s patented self-sealing vinyl cover protects the conductor from harsh environments, and ensures your cranes will have continuous power no matter the conditions. The Span-Guard crane power supply is available in 250 and 520 amps.

Tri-Bar/Four-Bar utilizes this same joint-free design but with three and four bar models. Created in the 1960s, this rugged system is a time-tested mobile electrification solution that can also be molded to specific, atypical layouts that may include bends, loops or ovals as opposed to the typical straight run of power. This flexible power supply is offered in 100 and 125 amps for your crane electrification needs. No matter where or how you’d like to use your cranes – Tri-Bar/Four-Bar can supply the power.

The latest editions to the U-S Safety Trolley line–PowerGlide and TightWire–are also used for crane electrification, and are available in 90 amps. With simplistic, lightweight designs, these systems were created with easy transport, installation and maintenance in mind; creating the perfect jib crane and gantry crane power supply solution. Supplied on a portable roll, both offer three or four solid copper conductors that are joint-free and ready to install for quick and easy access to power.

All four joint-free systems in the U-S Safety Trolley product suite have become the crane power supply of choice.
